China and Russia are enormous world powers. Kyrgyzstan and Tajikistan are small and fairly poor. What ensures that the SCO is more than just a China-Russia arrangement?

The member states will continue to strengthen the SCO as one of the pillars of the emerging more representative world order based on the supremacy of international law, primarily the UN Charter, respect for the civilisational diversity and peoples' independent choice of the path of their political and socioeconomic development.
